CARBURFETER FOR GAS-ENGINES.

Specification of Letters Patent. Patented Sept. 20, 1910- Application flied April 20, 1908. Serial No. 428,036.

To all whom it may concern:

Be it known that I, LOUIS C. Gamma, of Eltingville, in the borough of Richmond, city of New York, and State of New York, have invented a new and useful Carbureter for Gas-Engines, of which the following is a specification, reference being bad LO the accompanying drawin in which- Figure 1 is a vertica section partly in elevation, Fig. 2 is a horizontal section partly in plan.

In the operation of gas engines, especially gas engines which are used in driving motor cars, it is of great importance to secure a reliable and uniform mixture of the asolene t e combustible mixture which is supp ie d to -the engine cylinder. My invention efi'ects this I better than has been done heretofore.

' skilled mechanic.

In the drawing which shows the preferable it fromsupply pipe 3 controlled by a valve 4 and'fioat 5, these parts being of ordinary construction, and capable of variation by the 6 the carbureting chamber communicating. with the vessel 2 by means of supply nozzle 7 controlled by a regulating valve 8. The chamber 6 communicates with the atmosphere through an air port 9 which is controlled by a suitable valve 10 and which communicates with the port 11 leading to the engine cylinder by way of a passage which is controlled by a suitable throttle valve 12. This valve also preferably'cmrtrols an air supply port 13.

---The mixture of gas and air is drawn into the engine cylinder by suction caused by the piston of the cylinder, and the air is caused to mix efi'ectively withthe gasolene by the following device: 14 is an air supply jetpipe communicating at its outer end with the atmosphere and terminatingin proximity to the mouth of the nozzle 7, being directed at an oblique angle to the nozzle so that the air which passes through the ipe 14 will impinge upon the-stream, of gaso exie issuin from the-duct 7 and will tend to carry 1t laterally through the entrance to the port 11. WVhen the suction is created by the piston of the gas engine as above mentioned, it will draw a jet of airfrom the pipe 14 and this jet impinging upon the gasolene liquid issuing from the nozzle 7 will forcibly carry the gasolene and cause it to splash upon a gauze battle or. screen or screens 15 which fit over the mouth of the port 11, and the direction of the ports is such that the mixture of gasolene and air will strikethis scrcensidewise at an angle to the normal. In this way I secure a very effective mixture of the gas and air, and the strength of the stream of air through the ipe 14 may be varied by manipulation of t e valve 10, for the effect of closing this valve will be to cause a greater volume of air to enter through the pipe 14 and thus to increase the strength of the jet above mentioned and to increase the rate of flow of the gasolene.

The parts may be varied in many. ways, and within the scope of 'my invention as broadly defined it is n ot necessary that the gauze screens should be used or that the jet of air and gasolene should strike the same at an angle to the vertical, though these constructions are preferable.

I claim:

1. In acarbureting device, a mixing chamber having a port adapted to be connected with an engine cylinder and also having an air port, an adjustable valve controlling the air port, a throttle valve controllingthe engine port, afuel discharge nozzle extending into the said chamber, an air jet-pipe terminating adjacent to and behind the nozzle, and a perforated screen or battle in the engine port around the throttle valve, the air jet being arranged at an oblique angle to said screen to direct the mixed air and fuel against said screen at an angle to the plane thereof; substantially as described.

2. In a carbureting device, a mlXlDg chamber having a laterall extendin outlet provided with. a 'port a apted to e connected to an engine cylinder, a hollow cylindrical throttle valve seated in said extension and controlling saidport, a fuel discharge nozzle within said chamber, an air discharge pipe terminating adjacent to and behind the nozzle and directed toward the open end of the throttle valve, and the cusing having another air port controlled by the throttle; substantially as described.

In testimony whereof, I have hereunto set
